Question

(1+4x)*(1−4x+16x2) find the product

Answer 1

- B ± √ B2-4AC

x = ————————

2A

In our case, A = 4

B = -3

C = -1

Accordingly, B2 - 4AC =

9 - (-16) =

25

In our case, A = 4

B = -3

C = -1

Accordingly, B2 - 4AC =

9 - (-16) =

25

Applying the quadratic formula :

3 ± √ 25

x = —————

8

x = -1/4 = -0.250

x = 1

x = 0
